Going to an under 21 club. what should i do so im not an outcast/alone?

I'm 15, average looking, spanish who "acts like a white person" and I'm going to a club. I don't wanna be alone and just standing there. I wanna have fun, but not be a slut and try to get in everyone's pants. I just wanna know how to be social and flirty with a lot of guys.
